 narrow, contracted in front, with the hinder border nearly straight. 



Wing covers large, reaching beyond the end of the abdomen. 

 Wings often prolonged. Legs slender, and moderately long. 

 Tibiae all longer than the femora, those of the first two pairs with- 

 out spurs at the end ; the first pair somewhat dilated above the 

 middle, where they are provided with a little " drum" or auditory 

 sac on each side. Hind femora slightly swollen ; tibiae more or 

 less spiny ; tarsi with a pair of unequal spurs at the end of the 

 first joint.

CEcANTHDS NivEus. Serville. 

 Tree Cricket. (Fig. 7, male; Fig. 8, female.) 



Length, about three-fourths of an inch to the ends of the closed 

 wings. Color, pale whitish green, often changing to a lighter or 

 darker brown, frequently with brownish stripes 

 on the head. Two short black lines, one beyond 

 the other, on the under side of the base of the 

 antennae. 



These insects arrive at maturity in the autumn, 

 when the singing or shrilling of the males may 

 be heard. After pairing, the female forces her 

 ovipositor into the tender canes or branches of 

 the raspberry, grape, plum, peach and other 

 trees, depositing her eggs in a series, as shown in 

 Fig. 9. The canes are weakened in this way, and break down 

 easily. The eggs hatch in the early part of the next summer, and 

 the young feed at first on plant 

 lice, and later in the season on 

 the ripe fruits. 



The infested canes may be cut (Ecanfhus niveus. 



off and burned late in the fall or Female, side view. 



early in the spring ; and the mature insects ma}' be killed in the 

 fall by jaiTing the bushes on which they collect, causing them to 

 fall to the ground, where they may be crushed under the feet.
